IMPROVEMENT IN TOBACCO-CUTTING MACHINES.

Specification forming part of Letters Patent N0.f 204,7l5, dated June11, 1878; application filed March 23, 1878 To all whom it may concern: YI

Be it known that we, JAMES W. CROSSLEY, AUGUSTUS A. HAGEN, and GEORGE JUENGST, of New .York city, in the county and State of New York, haveinvented a new and useful Improvement in Tobacco-Cutting Machines, ofwhich the following is a specification:

Figure 1 is a vertical longitudinal section of our machine, takenthrough the line a- 90, Fig. 3. Fig. 2 is a front view of the same. Fig.3 is a top view of the same. Fig. 4 is a rear view of the same. Fig. 5is a detail section of the nut, screw, and follower.

Similar letters of reference indicate corresponding parts. v

The invention relates to an improved machine for cutting plug-tobacco;and it consists in a certain construction and combina tion of parts, ashereinafter described and claimed.

A is'the bed-plate of the machine, which is supported upon legs or aframe-work, B, of suitable height. To the upper side of the middle partof the bed-plate A is attached the feed-box C. To the forward edge ofthe bed-plate A and to the forward end of the feed-box G is attached aplate, D, in the middle part of which is formed. an openingcorresponding in size with the interior area of the feed-box, throughwhich the tobacco is forced out to be cut.

E is the knife-bar, which moves up and down along the forward side ofthe stationary plate D, and is held against the face of the said plateby bolts F and washers G, which bolts pass through-curved slots 01 inthe end parts of the stationary plate D. The washers G are placed uponthe inner side of the plate D, and are made of such a size as to extendbeyond the edges of the slots 01, and rest and slide upon the inner sideof the The knife-plate E is made right-angled in its cross-section onone side, as shown in Fig. 1, and to its outer or inclined face isbolted the knife H, which is slotted transversely from its upper edge,to receive the fastening bolts, so that it may be readily moved down asit wears. This construction enables the knife H to be arranged with thebeveled side of its edge inward, as shown in Fig. 1, so that by changingthe bevel of said edge the knife may be made to work with less or moregain, as may be desired.

To the ends of the knife-bar'E are pivoted the upper ends of two bentlevers, I, which are pivoted at their anglesto the forward edge of thebed-plate A, and the lower ends of which are connected by aconnecting-bar, J, so that the said levers may always be held exactlyparallel with each other, and may thus hold the knife H alwayshorizontal while making the cut.

To the lower end of one of the levers I is pivoted the end of aconnecting-bar, K, the

other end of which is pivoted to the crank or crank-wheel L, to whichthe power is applied for driving the machine. 7 V

The crank or crank-wheel L is attached to the end of the driving-shaftM, which rewolves in bearings in the'frame of the machine, and to theother endof which is attached a crank or slotted crank-wheel, N, fordriving the feed. v

To the crank Nis pivoted the end of the connecting-bar O, the other endof which is pivoted to the lower end of the arm P. The upper end of thearm P rides upon the hub of the driving-nut Q. In the outer edge of thedriving-nut Q are formed ratchet-teeth, with which engages the pawl R,which is pivoted to the arm P, and is held against the said nut Q by thespring S, also attached to the said arm P.

The nut Q is swiveled to the rear end of the feed-box O, and into itsscrew-thread is fitted the thread of the screw T. The forward end of thescrew T is swiveled to the follower U, by which the tobacco is pressedforward to be out. By this construction, as the nut Q is turned by thedriving mechanism, the screw T is forced forward, pressing the followerU against the tobacco placed in the forward part of the feed-box O.

The screw T is made hollow, and through its cavity is passed a rod, V.Upon the smooth outer end of the screw T is placed a collar, W, which isconnected with the outer end of the rod V by a screw or pin passingthrough the said collar and rod, and through the short longitudinal slotin the said screw T. To the inner end of the rod V is attached a smallcross-head, X, the ends of which project through the short longitudinalslot in the screw T, so as to enter slots or notches in the collar Y,attached to or formed upon the rear side of the follower U, around theforward end of the screw T. To the outer end of the screw T is attachedthe crank Z, for convenience in running the said screw back in withdrawing the follower for recharging the feedbox.

With this construction, when the feed-box O is filled, the rod Vispushed forward, so that its cross-head X may engage with the collar Y;then, as the feed-nut Q is revolved, the screw T is forced forward,forcing the follower U forward against the tobacco. When the follower Uis approaching the forward end of its movement the collar W strikesagainst the outer side of the nut Q, and as the screw T continues toadvance, the collar acts as a stop for the rod, so that cross-head X iswithdrawn from the collar Y, and the screw T turns with the nut Qwithout moving the follower U, so that it will be impossible for thefollower to be forced too far forward or the machinery to be broken.

The feed-nut Q is held from being turned back by the friction of thepawl R by the spring-pawl R, the engaging end of which rests against theteeth of the said nut.

If desired, the rod V may be placed in a longitudinal groove in the sideof the screw T; but we prefer the construction first described, as itleaves the threads of the screw T entire and allows the said rod V to bemade of any desired size.

It should be observed that the levers I and the connecting-bars J K maybe arranged above the knife-bar E, so as to leave the space below theknife H wholly unobstructed, the

said levers and bars being then entirely out of the way of the tobaccoas it falls from the knife.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-- 1. The combination of the bent levers I,the connecting-bar J, and the two bolts and washers F G with theknife-bar E, the stationary plate D, provided with the two curved slotsd, and the crank or crank-wheel L, substantially as herein shown anddescribed.

2. In a tobacco-cutting machine, the combination of the levers I I andconnecting bars J K, the knife-bar E, having its front side inclined,and the knife H, secured to said bar, with the beveled side of its edgeinward, in contact with the front plate or head of the machine, as shownand described.

3. In a tobacco-cutting machine, the combination of the revolving nut,the follower, the feed-screw swiveled thereto, and a clutch or key fortemporarily locking them together, and a connecting-rod or equivalentdevice, connected at its forward end to said clutch or key, and havingat its rear end a stop,'W, in
